Heck, I really don't know!
It's hard for me because that are few evolution lines that I like the fullest. Like, I love Dukemon, but I hate Guilmon and the others.
I guess I'd like to have Patamon as partner. Maybe a Kudamon.
As for the mon that is like me, I think it is Terriermon. He is easy going and sarcastic at the same time.
